mode: YIMP renders each menu in layout two times - for desktops and for mobile devices. In first case it sets this
prop to dmitrybtn\yimp\Yimp::DESKTOP, in second - to dmitrybtn\yimp\Yimp::MOBILE. If item's visibleMode prop is set, this item will be
rendered only if it's visibleMode value equals to this one.

items:

active: In original widget it is bool. Here it can be string, representing the mask, passed to dmitrybtn\yimp\RouteHelper::match(). If current route matches
this mask, item will be activated. For example, this property is set to orders/*, item will be active on
orders/create, orders/update, orders/item/create, and so on.

visibleMode: If you want to show menu item only on desktops, set it to Yimp::DESKTOP. For mobiles - YIMP::MOBILE.
